LUMBER-HANDLING ROLLER.

Application filed April 30,

To all whom it may. concern: 7. Be it known that we, EDWARD R. VVIIITE and MICHAEL J; THORNTON, citizens of the United States of America, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Lumber-Handling Rollers, of which the following is a specification.

Our invention relates to d'evicesfor. handling lumber, bar iron, pipes and other articles and the object is to provide a highly improved stand with'a roller in its top upon which lumber and other articles may rest and swing into any, position, required for handling such articles or for removing them from a pile a rack or a shed, car, eto.-'

In the accompanying drawing: .1 Fig. 1 is apartly sectional side elevation of the device complete gexcept forv special rollers used for certain purposes. Fig. 2 is a left hand end view-of the upper portion of Fig. 1.. Fig. 3 is a section on the line 3 in Fig. 1 Fig. 4 isa section on the line 4 4 in Fig. 1. -Fig. 5 is a partly sectional side view ofon'e of the special rollers already referred to. Fig. 6 is a section on the line 66 in Fig. 5.. Fig. 7' is a section-online 77 in Fig.5 1 of either one of the legs of the stand. Fig. 8 is a detail top View of the collar 75 in:Fig.-1. Fig. 9

is a side view of another special .roller. Fig.

10 is an enlargedsection on the line 10-.10

in Fig. 9. I 1

Referring to the drawings by reference numerals, the main stand is composed of a vertically disposed body tube 10 supported.

by four normally spread legsll. havingtheir lower ends provided. with shoes 12 pivoted at 13 to allow them to tilt and fall cular halves and clamped on the tube by bolts 19, one of the halves carrying the lugs 15 and the other half being a clamping band.

'By this arrangement two of the legs may easily be adjusted vertically. where the ground is uneven. I Y

. The body tube has several holes for a pin 21 to occupy andsupport the lower end 22 of an inner tube 23 which slides snugly 1n the body tube and has its lower end provided with several notches 24 to resist itsrotation upon the supporting pin 21. The 'topend of tube 231is provided with a fixed collar 25 the top ofwhich may have aball bearing 26. Said collar and ball bearing are fitted in a circular. groove 27 in a horizontally rotatable head 28 having two opposite arm's 29. The head and arms are preferably hollow and split into halves secured together bybolts30'and 31. On the latter bolt is placed the upper eye 32 of a coilspring33 the lower endof which has a hook, or eye, 34 placed-on a pin 35 in a gap 36 of a block 37, which is placed on a diametrically fixed pin 38 in the tube 23. It

will be noted that said block 37 and lugs 39 in Figs. 1 and 2 prevent loss of twisting motion of the head 28, as will be explained in the-operation.

4O 'isca horizontallydisposed roller preferably made with barbs 41 and guard flanges 42. Its journals 43 may be formed by the .ends of a shaft 44 extending through the roller. Beyond the flanges 42 one end of the roller has a cylindrical projection 45 engaged by a brake band46 one end of which is secured at 47 to a bracket 48 which is secured at 49 to one, of the arms 29, the

other end of the brake band being adjustably secured to the same bracket by a thumbnut50 by which the tension on the brake is regulated.- 7 1 The other end. of-the roller is, provided with ratchet teeth 51 engagedby a pawl 52 pivoted at 53 to a bracket 54,- which. is secured at 55 .tothe-adjaeent arm 29 and has a spring 56 tending to'hold the pawl e11- gaged o'r disengaged'when the latter is brought to one of the positions 52 inFig. 3. The journal boxes 57 are each formed with aca hin 'ed at 58 see Fi 2 and havin p b C 23 a gap 59, in and out of which may be swung a bolt 6O pivoted at 61 and having a thumb nut 62. This arrangement enables the .operator to readily remove the main roller 40 and substitute special rollers better adapted for special work. Of such special rollers we have shown one in Fig. 5. It has a plain body 40%but'upon that bodyis .placed a collar 63 .having a peripheral groove 64. ":The collar may be made in halves and clampedin place by blts.65 so as. tomake itieas ilyexchangeable for a collar. with a different form of groove 64. Fig. also helps to explain how either roller may be formed of a shaft l4 having hubs 66 secured at 67 and the body of the roller maybe a pipe'having each end held either in an annular groove 68 or -by,a :projection-,69;ot the hub entering into the tube. as to-thelleft in; Fig 5.

In. the operation of the dev1ce,: each plank 'or other piece of'lumber to be moved is placed across therollerlll-and pushed to ward :itsg-destmatlon in a rallwayvcarqor upon a,-pile ofwlumber or away therefrom,

one manvpushing the -=plank; in the. desired direction and another .manreceiving. it and piling 1t. During suchoperatlon 1t is often vnecessary toiehange othe direction of the plahl'r While it rests on the roller and in t :doingso:.the head 26 swivels on its joint 26-127 and lets the roller deliver. thelumber =in afery handy position to the personreceivingit but astthiswoulda leave'jthe roller in as poor positionrforiplacingthe next plank .or-boardmponit; the spring 33 is relied on rtozrestoretheihead 26"and thereby the roller toxthenormal: position automatically-by thetorsional'iforce of the spring. Such: nor- .mal .apositiolr may from time to time be altered without moving the legs 0t the stand" on the ground: or other su1- porting surface; the operator simplyl=i=fts the head 26 and arms 29 slightly and turns the inner itnbe with other-of itsbottom notches 24:

upon the pin 21. VVhenever raising or lowf ering of the roller is desired the pin 2l is :mov ed toa different hole 2O int-he body tube' lO. V

lVhen planks or-otherhcavy pieces of lumber while onthe roller, getmuoh higher atoneend thanf atthe other the weight ot the lumber tends to rotate the roller and move downward, 'ltis to overcome such tendency-that the roller isgiven the'burs 451 and br-ake 4;6'50, and for handling very heavy lumber also the ratchet wheel ar na pawl 52' All this refers to l ahdlingot- 1 rough lumber.

llslidable collars '69: having adj acent flangesa 70,,and each of; them. carries a radially slidtable catch=71- whose inner end is normally -lengagedin-one of the cavities- 68 by a com- ;p'ress1onc011 sprlng' 73 .(shown in Fig. 10) ezacilrellng the catch and'pressingagainst a collar fixed or formed near its inner end. The outer end is formed with a head serving as a.- tinger hold to bevpulled; outward in releasing the :eatch during the adjusting ..o..the icollars toward or away from the middleportion of the. roller. ,In using. this roller, flth'e. collars .are spread. .or I. closed to form an 7 intermediate annular space or grooye javabout the width of the board, plank or other material handled, so that. ain:changing.1the. ;direction of the plank the latter will engage the flanges and cause the head 28 t0= turn-and leave the pla nlcin 'a transversewposition oil-lithe roller. trThezeame is: theieasel if: :barl ironeorpipes are handled over ttheuroller.
